[0024] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0025] Please see Figures 1-8 This utility model provides a technical solution:

[0026] An automatic testing device for the life of a grounding switch includes a test base 1, a grounding switch body 2 on top of the test base 1, two pairs of support bases 3 symmetrically installed at the bottom of the grounding switch body 2, movable slots 4 symmetrically opened on both sides of the top of the test base 1, hydraulic cylinders 5 fixedly connected to the inner sidewall of the movable slots 4, positioning components 6 on the output end of the hydraulic cylinders 5, a drive shaft 7 installed on the grounding switch body 2, a fixed bracket 8 fixedly connected to one side wall of the test base 1, a swing mechanism 9 fixedly connected to the top of the fixed bracket 8, and a connecting component 10 on the output end of the swing mechanism 9.

[0027] The positioning component 6 includes a movable block 601 fixedly connected to the output end of the hydraulic cylinder 5. The movable block 601 is slidably connected in the movable groove 4. A connecting block 602 is fixedly connected to the top of the movable block 601. An L-shaped positioning bracket 603 is hinged to the connecting block 602. A positioning screw 604 is threaded through and threaded onto the positioning bracket 603. An adjusting knob 605 is fixedly connected to the top of the positioning screw 604. A positioning pressure plate 606 is fixedly connected to the bottom of the positioning screw 604. The positioning component 6 can position the support base 3 and the grounding switch body 2. Therefore, during the test of the grounding switch body 2, it is not easy for the grounding switch body 2 to shift or fall, thereby avoiding affecting the normal conduct of the test of the grounding switch body 2. The connecting component 10 includes an upper connecting sleeve 1001 fixedly connected to the output end of the swing mechanism 9 and a lower connecting sleeve 1002 symmetrically arranged below the upper connecting sleeve 1001. The upper connecting sleeve 1001 and the lower connecting sleeve 1002 are connected to each other. One end of 02 is rotatably connected via a hinge shaft. The other ends of the upper connecting sleeve 1001 and the lower connecting sleeve 1002 are both fixedly connected to a connecting support plate 1003. Connecting bolts 1004 for threaded connection are symmetrically passed through the connecting support plate 1003. The inner sides of the upper connecting sleeve 1001 and the lower connecting sleeve 1002 are provided with rubber pads 1005 of matching specifications. Mounting blocks 1006 are arranged and fixedly connected at equal intervals on the rubber pads 1005. Several mounting slots 1007 of the same number, corresponding position and matching specifications as the mounting blocks 1006 are arranged at equal intervals on the inner walls of the upper connecting sleeve 1001 and the lower connecting sleeve 1002. The connecting assembly 10 can provide a good connection between the output end of the swing mechanism 9 and one end of the transmission shaft 7. Therefore, during the test of the grounding switch body 2, it is not easy for it to loosen or fall off with the transmission shaft 7 on the grounding switch body 2, thereby avoiding affecting the normal test of the grounding switch body 2.

[0028] Workflow: First, all electrical appliances are powered on and connected to external controllers. The test base 1 provides placement space and support for the life test of the grounding switch body 2. The support base 3 supports the grounding switch body 2. The movable slot 4 provides installation space for the hydraulic cylinder 5. The hydraulic cylinder 5 can adjust the horizontal position of the positioning component 6 through its extension and retraction. Therefore, it can be adaptively adjusted to grounding switch bodies 2 of different specifications, thereby improving the applicability of the positioning component 6. The positioning component 6 can position the support base 3 and the grounding switch body simultaneously. Therefore, during the test of the grounding switch body 2, it is not easy for the grounding switch body 2 to shift position or fall. To avoid affecting the normal testing of the grounding switch body 2, when fixing the support base 3, first activate the hydraulic cylinder 5, causing it to move the movable block 601 within the movable groove 4 through its extension and retraction. After adjusting the movable block 601 to the appropriate position, rotate the positioning bracket 603 on the connecting block 602 above the support base 3, and drive the positioning screw 604 downward by adjusting the knob 605. Finally, the support base 3 is positioned by the tight fit between the positioning plate 606 and the support base 3. The same principle applies when removing the grounding switch body 2. The transmission shaft 7 can drive the test part of the grounding switch body 2 to move, and the fixed bracket 8 can support the swing mechanism 9 to ensure the structural stability of the swing mechanism 9 during the test. The swing mechanism 9 can drive the connecting assembly 10 to swing. The connecting assembly 10 can provide a good connection between the output end of the swing mechanism 9 and one end of the drive shaft 7. Therefore, during the test of the grounding switch body 2, it is not easy for the drive shaft 7 on the grounding switch body 2 to become loose or fall off, thereby avoiding affecting the normal test of the grounding switch body 2. When connecting with the drive shaft 7, first place one end of the drive shaft 7 under the upper connecting sleeve 1001, and rotate the lower connecting sleeve 1002 upward so that the upper connecting sleeve 1001 and the lower connecting sleeve 1002 cover the outer side of the end of the drive shaft 7. At this time, the two connecting support plates 1003 are in contact with each other. Finally, screw the connecting bolt 1004 into the connecting support plate 1003. Similarly, during disassembly, the rubber pad 1005 not only increases the friction between the upper connecting sleeve 1001 and the lower connecting sleeve 1002 and the drive shaft 7, but also provides good protection for the drive shaft 7. Therefore, it can prevent scratch damage caused by contact between the upper connecting sleeve 1001 and the lower connecting sleeve 1002 and the end of the drive shaft 7. Furthermore, due to the flexible structure of the rubber pad 1005, it can be disassembled and replaced when its protective effect is affected by damage. During installation, the rubber pad 1005 is first placed inside the upper connecting sleeve 1001 and the lower connecting sleeve 1002, and then the mounting clip 1006 on it is inserted into the corresponding mounting slot 1007 for engagement. Disassembly is similar. During testing, the swing mechanism 9 is activated.The connecting component 10 drives the drive shaft 7 to swing synchronously, and the drive shaft 7 drives the moving contact in the grounding switch body 2 to swing back and forth, thereby testing its service life.
